pub fn follow_switches(on: &[String], off: &[String]) -> boolExpand description
The marks of switched-off accounts made to follow the configuration, on
this device: the mark is this device’s own, while the configuration
travels; an account switched on again elsewhere (or here before, in a
window that died) kept its mark here, and its calendars and address
books, synced all the same, never showed (the phone of 21 October 2026).
on: the accounts switched on; off: those switched off. Whether any mark changed.
